Hi,

As per title and I also find out it able to reproduce in the demo site: https://demos.telerik.com/aspnet-ajax/editor/examples/overview/defaultcs.aspx

Step:

1. Change to 'HTML' mode.

2. Open 'Find And Replace' dialog.

3. Enter a word to find and hit the 'Find' button.

Notice that the word does not get highlighted. It only happens in 'HTML' mode, 'Design' mode working fine.

Please help as this feature is very useful in my project.

Thank you.

The Switch component with Bootstrap skin looks odd. It is almost invisible in off state, and lacks a border around it when in on state.

This can be observed in the live demos site: https://demos.telerik.com/aspnet-ajax/switch/overview/defaultcs.aspx?skin=Bootstrap 

Steps to Reproduce

1. Open a page containing RadEditor with some content in it
2. In Design mode, select all text (Ctrl+A)
3. Delete the selected text
4. Switch to HTML mode
5. Switch back to Design mode
6. Press Ctrl+Z (Undo) a couple of times.
   

• A JavaScript error is thrown in the browser console
• The undo operation fails to restore the deleted content
• Error occurs in _updateBrowserRangeStart method when calling this.range.setStart(e, t)

Expected Result

• The undo operation should work without errors
• The previously deleted text should be restored
• No JavaScript errors should appear in the console

Provide keyboard support for the MediaPlayer.

Some of the occurring problems are:

• It is not clear how to get focus on the control, we assigned an accesskey="T" but  alt-t doesn't give focus (we have  a radmenu on the same page with an accesskey="M" which works fine)
• The tab key sometimes does not work.

Keyboard navigation is required for 508 accessibility support. Generally the space bar is used to start/stop video and tabs are used to access the playbar features like expand, vol and CC

ChatGPT recommended "Turn off Telerik’s “old” ARIA settings (they are overly strict and often invalid):"

i removed it and it worked. WTH?

What i supposed to do now? I added these settings in all our products

Hi, 

We need to add an aria-label attribute to the RadEditor toolbar link buttons to match the title attribute text. I have been successful using JQuery on other controls to improve accessibility, but this one is not working. It appears because the link button is not rendered since is a pseudo element using the ::before. I have been unable to inject the attribute on page load. 

The issue is for screen readers the editor buttons are not announced when using the arrow key navigation which is called virtual mode. The buttons do announce when using the tab key which is called forms mode.

If this can be a bug fix it would benefit everyone, otherwise, if you have a code suggestions that is helpful. Image attached. 

Thank you.

We discovered the following is not working in RadGrid's ItemDataBound nor in ItemCreated events:

            Dim imgbtn As ElasticButton
            Dim imgbtn1 As ElasticButton
            imgbtn = DirectCast(Item("btn_sequp").Controls(0), ElasticButton)
            imgbtn1 = DirectCast(Item("btn_seqdown").Controls(0), ElasticButton)
            imgbtn.SecondSpanClass = "d-none"
            imgbtn1.SecondSpanClass = "d-none"

So we had to set through CSS like:

We have noticed that when you choose 'Yearly' in the recurrence editor that the text 'Recur every' shows up twice in the editor. If you change it to 'Monthly' or any other type of recurrence, this does not happen, and the text only shows up once.

The issue can be replicated in Binding to Generic List live demo.

I have a RadEditor that is rendered in mobile mode on a mobile device emulator in Chrome browser.
For this editor, I have subscribed to OnClientCommandExecuted event. The event fires, but the problem is that it fires twice for ToggleScreenMode command.
To reproduce this issue, you can use the page code below and render it in Chrome mobile emulator; then press on edit pencil button followed by clicking the check button.

1. In Design mode, select all text (Ctrl + A) and delete it.
2. Switch to HTML mode.
3. Switch back to Design mode.
4. Press Ctrl + Z (Undo).

• The first Ctrl + Z has no effect; the deleted text is restored only after pressing Ctrl + Z a second time.

WAVE tool indicates errors in RadTreeView when CheckBoxes are enabled for the Control:

While the Keyboard navigation is enabled, navigating through the items using the UP/DOWN arrows does mark the rows active, however, the active styles remain for the rows even if they aren't active anymore.

The issue happens when using the ActiveItemStyle element to define the styles (e.g. ForeColor, BackColor, etc.). Works as expected using the default styles.

Code to replicate the issue

<script runat="server">
    protected void RadGrid1_NeedDataSource(object sender, GridNeedDataSourceEventArgs e)
    {
        (sender as RadGrid).DataSource = Enumerable.Range(1, 5).Select(x => new
        {
            OrderID = x,
            OrderDate = DateTime.Now.Date.AddDays(x),
            Freight = x * 0.1m,
            ShipName = "Name " + x,
            ShipCountry = "Country " + x
        }).ToList();
    }
</script>

<telerik:RadGrid ID="RadGrid1" runat="server" RenderMode="Lightweight" OnNeedDataSource="RadGrid1_NeedDataSource">
    <ActiveItemStyle BackColor="Red" ForeColor="White" />
    <ClientSettings AllowKeyboardNavigation="true">

When using client-side code to filter my Grid, the "BETWEEN" filter does not work well when filtering DateTime values where the time is after 12:00 AM.

i.e., filtering the dates between 9/11/2025 and 9/12/2025 does not include 9/12/2025 at 12:01 AM or any date where the time is after 12:00 AM.

Additionally, when passing datetime values to the filter function, the time component is dropped afterward.

var filter = "9/11/2025,12:00:00,AM 9/12/2025,11:59:59,PM"
tableView.filter(columnName, filter, "Between");

Change the skin of the radeditor in the default.aspx to another skin such as "metro" and the problem will not happen.    It works OK at least on Black, Metro and Silk but haven't tested others, you can tell it doesn't work when the divider bars in the editor toolbar don't appear properly.

I recently upgraded the Telerik version from 2025.1.416 to 2025.3.825, and started getting this NullReferenceException during debugging.

I noticed I get the error when debugging RadGrid with the Skin property.

The Box Plot Chart throws the following errors when used:
